This momentary diversion of the attention and energies of his neighbours was most propitious for Orkhan. Andronicus had rendered him good service. It gave to Orkhan an opportunity of enlarging and rounding out his dominions without incurring opposition that would not only have prevented him from carrying out his schemes but might also have destroyed him. Orkhan had been waiting for this moment. In 1333, the Turcoman emir of Mysia had died. His younger son had taken refuge with Orkhan, and promised in return for aid in dispossessing his brother to surrender to the Osmanlis Balikesri and three other border cities. Orkhan could not act immediately. He contented himself with advising the elder brother to divide his dominions with Tursun. Tursun went to negotiate in person, and was killed by his brother. This was shortly before the expedition to Phocaea. Orkhan was now ready. He put in the field an expedition, ostensibly to punish the assassination of his protégé Tursun, and was so successful that he forced the emir of Karasi to give up Pergamos and go into exile in Brusa.[123] In another expedition, which probably occurred in [Illustration: THE EMIRATES OF OSMAN AND ORKHAN] 1337 at the earliest,[124] Orkhan added Mikhalitsch, Ulubad, and Kermasti to his dominions. He was now virtually master of Mysia. This was the extent of Orkhan’s conquests in Asia Minor. It is necessary to emphasize this point, owing to the erroneous idea which has so long been accepted and which has found its way into many modern writers.[125] No corroboration can be found for the statement of Cantacuzenos that Soleiman captured Angora from the Tartars in 1354.[126] Aside from this, neither Byzantines nor Osmanlis report any further conquests of Orkhan in Asia Minor. From the fact that there is a complete silence as to their fate, it is reasonable to suppose that the Osmanlis during the last decade of Orkhan’s reign destroyed the independence of several little states of which Ibn Batutah and Shehabeddin report the existence between 1334 and 1349.[127] But these were all in a general sense either included in Mysia (Karasi) or in the territory which Orkhan is popularly supposed to have inherited from Osman.[128] After the Mysian expedition and the fall of Nicomedia, Orkhan may be regarded as the acknowledged sovereign of a definite state. We have good contemporary testimony to his character, his power and his reputation at this period just before he became an active factor in deciding the destinies of the Byzantine Empire.
